A battery with an emf of 7.9 V and internal resistance of 1.37 Ω is connected across a load resistor
R.If the current in the circuit is 0.88 A, what is the value of R?
Answer in units of Ω
What power is dissipated in the internal resistance of the battery?
Answer in units of W
How do you set this problem up?
